Solar Street Light Quality Control

Strict Quality Inspection from Raw Materials to Finished Products

At Anern, we understand that solar street lights operate outdoors for extended periods and must withstand challenging weather conditions, including high temperatures, heavy rain, strong winds, and extreme cold. For this reason, we have established a comprehensive quality control system covering raw material procurement, manufacturing, performance testing, aging tests, final inspection, packaging, and shipment.

This complete quality management process ensures that every solar street light delivers stable, efficient, and durable performance.

Supported by strict quality management procedures and advanced testing equipment, Anern continues to provide reliable solar street light solutions for municipal roads, rural roads, industrial parks, commercial projects, and government infrastructure projects worldwide.

Incoming Quality Control (IQC)

High-quality solar street lights begin with high-quality core components.

Before entering the production line, all raw materials undergo strict inspection to ensure compliance with product design requirements and quality standards.

Main Components Inspected

• Monocrystalline solar panels

• Lithium iron phosphate (LiFePO₄) batteries

• LED chips

• MPPT smart controllers

• Aluminum-alloy lamp housings

• Lamp-post mounting accessories

• Waterproof connectors and cables

Inspection Items

• Appearance quality

• Dimensional specifications

• Electrical performance

• Material consistency

• Supplier quality verification

Only materials that pass IQC inspection may enter the production process.

In-Process Quality Control (IPQC)

During production, we implement real-time quality monitoring at every stage to ensure assembly precision and process consistency.

Main Inspection Items

• LED module installation

• Battery component assembly

• Controller wiring inspection

• Solar panel installation

• Waterproof sealing inspection

• Screw torque testing

• Complete circuit inspection

Through continuous process inspections and sampling checks, we effectively control product quality and reduce the rate of manufacturing defects.

Product Performance Testing

Before shipment, every solar street light undergoes comprehensive performance testing to ensure that its actual operating performance meets the design requirements.

Battery Charge and Discharge Testing

The battery test evaluates:

• Battery capacity

• Charging efficiency

• Discharge duration

• Overcharge and over-discharge protection

• Battery cycle performance

These tests ensure that the battery can provide stable power throughout the night.

Solar Charging Test

We simulate real-world lighting conditions to evaluate the performance of the solar charging system.

Main Test Items

• Photovoltaic conversion efficiency

• MPPT charging efficiency

• Controller operating stability

• Automatic charging and discharging functions

These tests help ensure that the system maintains reliable energy storage performance, even during cloudy or rainy weather.

LED Lighting Test

The LED lighting test includes:

• Luminous flux

• Power output

• Color temperature

• Beam angle

• Illumination uniformity

These inspections ensure that every solar street light meets the required lighting performance standards.

Smart Control Testing

For smart solar street lights, we test the following functions:

• Photocell control

• PIR motion-sensing function

• Automatic dimming modes

• Timer control functions

These tests ensure that the intelligent lighting system operates reliably while improving energy efficiency.

Waterproof Performance Testing

Solar street lights remain installed outdoors for long periods and must provide reliable protection against water and moisture.

We conduct multiple waterproofing inspections, including:

• Waterproof sealing inspection

• Waterproof structural inspection

• Simulated rain testing

• IP65/IP66 protection rating verification

These tests ensure that the products can operate reliably for extended periods in heavy rain, high humidity, high temperatures, and other harsh outdoor conditions.

Aging Test

Every batch of solar street lights undergoes continuous aging testing to verify long-term operating stability.

Typical Aging Test Durations

• 24 hours

• 48 hours

• 72 hours, depending on product requirements

  
  

During the aging test, we continuously monitor:

• LED brightness stability

• Controller operating status

• Battery performance

• Product temperature rise

• Overall system operating stability

Aging tests help identify potential early-stage failures and effectively reduce the early failure rate of the products.

Final Quality Control (FQC)

After assembly, a professional QC team performs a final inspection of each finished product.

Main Final Inspection Items

• Appearance inspection

• Lighting test

• Charging test

• Functional testing

• Motion-sensing function test

• Label inspection

• Accessory verification

• Packaging inspection

Every product must pass final inspection before it can be shipped.

Packaging and Shipment Inspection

To ensure that the products arrive safely and without damage during international transportation, we conduct strict packaging inspections.

Main Inspection Items

• Outer-carton strength testing

• Shock-protection inspection

• Product label verification

• Packing-quantity confirmation

• Export packaging standard inspection

These procedures help ensure that every solar street light reaches customers around the world safely and securely.
